Signaling and data for each group of four framers are multiplexed on framers 1 and 5 signaling and data leads for
HMVIP/H.100 Mode.
For 208-lead PBGA, the Line Interface Control and Monitor Interface Control share leads based on the ESPBMON bit
state, and TTSIGn/RTSIGn share leads with TTAUXn/RTAUXn based on the FTIM bit state.
